Transcript of 5th Grade-Ch. 9 Lesson 1 What is the Structure of Earth
Ch. 9 Lesson 1What is the structure of
Earth?
4 layers of Earth
The Structure of Earth's Interior [01:32]
Another Structure of the earth animation
crustoutermost, thinnest
layer
continental crust oceanic crust
made of granite- incl. continents
made of basalt- incl. ocean floor-
6-11 km thick
continental rise= beginning of oceanic
crust
mantle
solid hot rock- can flow like
liquid
top part + crust
lithosphere
Structure of the Earth animation-Shows currents in mantle
core-center
made mostly of iron
2 parts:magnetic
field
outer core-liquid
(flows in currents)
inner core-solid
The Four Layers of the Earth's Interior: Inner Core, Outer Core, Mantle, and Crust [01:16]
Ways scientists study Earth’s interior
1. study mantle material from cracks
2. measure earthquake vibrations-
seismograph3. test materials to see how
respond to heat & pressure
The Mantle: The Asthenosphere, Upper Mantle, and Lower Mantle [02:29]

The Earth Bowl• The homework monitor will need to get a tray which
contains the following: A plastic baggie, with graham
cracker.Nilla wafer cookies
A container of black cherry Jell-O
A container of lemon Jell-OA spoonA bowl
DO NOT TOUCH ANY OF THE MATERIALS AFTER YOU HAVE RECEIVED THEM. WAIT UNTIL I
EXPLAIN WHAT TO DO.
Steps to Making the Layers of the Earth!1) Put marshmallow in the bottom of the cup.
2) Next, lemon Jell-O and put it in the bowl.
3) Then, put black cherry Jell-O on top of the lemon Jell-O.
4) Last, you will need the plastic baggie containing graham crackers. Break the graham crackers up in the bag. DO NOT POUND TOO HARD! YOU DON’T WANT THE BAG TO BREAK! Sprinkle the crumbs on top of the black cherry Jell-O.
You have now made the Layers of the Earth.
*The Crust (graham crackers)*The Mantle (black cherry)* The Outer Core (orange)* The Outer Core (orange)
* The Inner Core (marshmallow)
Draw a picture of it in your notebook, labeling it with the
name of the layer and the ingredient.
